  2. The objectives of the APCS • increase the speed of process control; • ensuring continuity of technological processes; • Localization of emergency parts and equipment failure; • improving the safety of operation of the technological process; • greater automation of operations control and protection through the use of information-gathering modern microprocessor controllers and software; • reduce losses of chemical and petrochemical products through including them in the reception, storage and shipment; • obtain the generalized parameters of the object; • improve the efficiency of staff.

  3. System Composition

  4. The system includes: • nodes including the mass of petroleum products shipped in a tanker based on flow:- Accounting oil • - fuel oil accounting • - accounting diesel fuel • - gasoline accounting • - accounting kerosene.

  5. The system includes: • Radar Levels (at each vertical tank) • Sensors measure the density • Sensors measure levels • Management system • Laser scanning system of tanks based on the electronic total station • Torboforcer calibration rig based on compact-prover • controller's office • Wireless data transmission systems , uninterruptible power supplies, diesel generators and other equipment.

  6. Custody of shipped in tankers products by nodes into account by measuring the mass, density and temperature of the product by the dynamic method using Coriolis flowmeters. • Custody of stored in the tanks of petroleum products by measuring the level, temperature and density followed by calculation of the mass of the product. To ensure the required accuracy of measurements applied to Radar Level modules multipoint temperature measurement of petroleum products in tanks, as well as sensors for measuring the level of produced water.

  7. Mass of oil in reservoirs is calculated on the basis of data obtained from the radar level gauges and sensors density • The system of data collection and processing is an integrated information system for the management of industrial and business processes. Along with the economic units are designed for process control terminal delivery in real time.

  8. The system allows: • - Monitor and manage all technical processes; • - Simplify the decision-making and avoid mistakesof controllers and operators; • - Conducta full or partial flow of documents • - Store, transmit and process the information.

  9. The main advantages of the system: • - Simplification of regulations and shipment; • - Reducing the time of shipment tanker approximately 30% due to the exclusion of operations sealing of valves, gauging the level in the tanks and tankers, bursting pipes (with on-loads of petroleum products of one species), excluding part of the accompanying documents; • - Issuing the results immediately after loading; • - Operational transfer current data;

  10. The main advantages of the system: • - Simplified procedure of the Commission on Shipping; • - Decreases the measurement error when shipping in tankers through the metering stations; • - Stricter controls over the unauthorized release of petroleum products; • - Reduced losses in the straits into the ground and play during the filling of reservoirs; • - System architecture provides users with important information on the causes of problems and recommended actions to address them;

  11. The main advantages of the system: • - Increase productivity and profitability; • - To provide immediate notification of the presence of a critical situation; • - Improve the accuracy of oil products in tanks at the expense of the laser scanning tanks and Refined calibration spreadsheet; • - Prediction and prevention of equipment failure;

  12. The main advantages of the system: • A self-test software and hardware tools and diagnostic uncertainty of values taken from the sensors and the primary transformers; • On a single platform integrated products for process automation (APCS) and business processes (AMSBP); • Provides multilayered security of current and historical data of the system and commercial information.

  13. Metrological support • Flow metering - by periodically checking the compact-prover. • The Laser Levels - by comparing 3D laser calibration vertical tank gauges and measuring results.

  14. Truboforcer calibration rig-based compact-prover is a set of measuring tools enabling fast and the required service level to produce a periodic calibration as metering, and most truboforcer installation, thereby providing the desired high precision mass measurements shipped a tanker of petroleum products.

  15. Description of the basic elements of the system

  16. Description of the basic elements of the system Nodes account created and compiled on the basis of mass flow. The principle of the dynamic mass flow based on the Coriolis force.

  17. Composition Metering: • Measuring platform, assembled in a single form factor with two measuring lines; • Collection and information processing Case from computers for each measurement platform.

  18. Each computer consumption function as a standalone device, it performs the following functions: • Receives the signals from sensors installed on the measuring system. • Calculates the total consumption during the period and per day. • Passes through the serial communication channel at the request of a central computer with the results of measurements and calculations. • Displays all measured and calculated parameters. • Sends alarms to a central computer for documenting and alerting the operator. • Displays totals with sufficient resolution to accumulate for the period up to three months without an overflow.

  22. The advantages of using metering • Configuring metering in accordance with the requirements of the technological scheme, ease of use and service; • High accuracy is not dependent on the composition of the product and the presence of air in the measuring line; • Ability to work in a wide range of flow with a nominal error; • Durability, lack of moving, wearing parts; • The presence of cold reserve.

  23. The system based on radar level gauges performs the following tasks: • conducting a trade oil products in tanks; • constant monitoring of tank farms (unauthorized access, leaks, accidents).

  24. The radar system includes: • Radar levels; • Temperature sensor in the reservoir; • Sensors of produced water; • Modules of the field connections to poll all tanks; • PC with specialized software.

  25. Radar System • Level gauge operates in automatic calibration - and produces 6 measurements of the product in the second. Prior to each measurement level gauge produces selftest - on signal processing circuit is fed test "reflected from the surface" signal, and if the output is obtained in advance a certain "level of product value," then proceed to the actual level gauge measurements. In the case of significant deviations of the results of processing the test signal from the normal level gauge gives a signal about his failure. Level gauges do not require periodic calibration on special stands. The system TRL / 2 gauges produced water to the volume of produced water in the reservoir in the calculations of volume and mass of the stored product.

  26. Advantages of Radar Levels System • The process of measuring the level does not affect the state of the gas medium tank, the presence of dust and fine sediment, as well as the variety of the product; • Software a central computer system provided with menus and dialog windows of various information to the operator; • High accuracy measurement; • Digital reference and thermostabilisation exclude additional errors.

  27. Density Sensor • The sensor is mounted at the bottom of the tank and is designed for measuring the pressure of oil column with subsequent calculation of the density of oil products with an accuracy of 0,001 2/sm3. Thanks to install the sensor, significantly increases the accuracy of measuring the mass of oil stored in tanks. All oil storage tanks are equipped with sensors emergency level. Sensor alarm levels are designed to provide early warning of personnel tank farm on the achievement of the lower limit, upper limit, as well as top-level emergency fill the tanks. Information reaching the ceiling (sound and light) is displayed on directly from the reservoir and is transmitted remotely to control center, displayed on the screen of the system.

  28. Complex automated system consists of: • monitoring the level of fuel in the tanks with the functions of measuring the mass of oil in the tanks; • control system for leaks, and siphoning off of petroleum products; • control system for transfer within the facility; • system of measuring the mass of petroleum products shipped in tankers by the dynamic method; • monitoring program malfunctions, errors, and "Alarm" systems; • data transfernode.
